SFECIFICATION forming part of Letters Patent No. 395,567, dated January1, 1889.

Application filed April 12, 1888- erial No. 270,427. (No model.)

To all z/xhom/ it may 0072067 70.

Be it known that I, JlUsTAv L. J AEGER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Machines forApplyingCori'ier-Stays to Boxes, of which the following is a specification.

This invention relates to a machine for applying corner-stays to boxes,the corner-stays being cut out to the required length and width and thenrendered adhesive one after the other, each stay after having beenrendered adhesive being carried over the corner of a box and thensecured to said box by pressure, as fully pointed out in the followingspecification and claims, and illustrated in the accompanyin drawings,in which-- Figure 1 represents a side elevation, partly in section,showing the machine in its position of rest. Fig. 2 :is a similar viewshowing the working parts in a different position from that shown inFig. 1. Fig. 3 is a transverse Vertical section in the plane as, Fig. 2.Fig. 4 is a detached side elevation of the picker,- partly in section.Fig. 4* is a detached face view of said picker. Fig. 5 is a perspectiveview of the holder for receiving and retaining a pile of thecorner-stays. Fig. [5 is a perspective view of one of the corner-stays.Fig. 7 is a perspective view of a box. provided with corner-staysSimilar letters indicate corresponding parts.

In the drawings, the letter A designates the table, which rests uponlegs 15, and from which rises the standard 0. On the outer end of thisstandard are formed guides D D, lJGtVGGll which is fitted the shank F.ofthe punch E.

F is the box-support, which is firmly seen red to the table A, and thesides of which are inclined, so as to fit the corner of the box V.

(See Fig. The face of the punch E is formed to correspond to theinclined sides of the box-support F, and in said face is formed acavity, b, the object of which will be presently explained.

The stays a are made of paper, muslin, or any other suitable flexiblematerial, and they are cut out to correspond in length and width to thesize of the boxes for which they are to be used. These stays may beintroduced into the machine in a plain state and afterward renderedadhesive by the ap jdication of paste, or said stays may be previouslyprepared by coating one side of each with a suitable adhesive-sueh asmucilage-which is left to dry; and if such previously-prepared stays areused they are afterward rendered adhesive by the application ofmoisture. The stays, whether plain or previously prepared, are formedinto a pile and introduced into a holder, G. A perspective view of thisholder is shown in. Fig. 5. It composed of a bottom, c, and two endplates, (1, which are adjustable on the bottom and the upper ends ofwhich are provided with hooks e. 011 the bottom 0 is placed a spiralspring, f,which forces the pile of stays up against the hooks c. On thetable A are cast or otherwise secured two plates, g, to which the holderG is at tached by screws h.

Above the table A are situated two guides, H H, between which is fittedthe cross-head I, and in this cross-head is firmly secured a stud, 1',which forms the fulcrum for a bellerank lever, J K. The inner end of thelong a m J of this belLcrank lever is rounded and carries the picker L,which consists of two wings, j j, Fig. l, swinging upon the rounded endof the arm J and acted. upon by a spring, which has a tendency to throwsaid wings open in the manner of a spring-hinge, so that they lie flatupon the uppermost stay in the holder G, Fig. 1.

Then the bell-crank lever J K is in the position shown in Fig. 1, itsshort arm K bears against a stud, 7c, secured in a lug projecting fromone of the guides 11, and the picker L is depressed upon the uppermoststay in the holder G; but as soon as the bell-crank lever J K is movedforward toward the punch E the picker L and uppermost stay are withdrawnfrom the holder. In order to accomplish this purpose, the picker isprovided with projections which are provided with an adhesive, as willbe hereinafter described.

The movements of the bell-crank lever J K are produced by the combinedaction of an elbow-lever, M N, and a cam-groove, O. This elbow-lever hasits fulcrum on a stud, l, in the standard 0, and its long arm M isconnected to the long arm J of the bell-crank lever J K by a pivot, on,while its short arm N carries a roller-stud, a, which engages thecam-groove 0. This cam-groove is formed in the outer surface of thefoot-lever P, which extends down through the table and has its fulcrumon the stud 0. A weight, V, has a tendency to throw this foot-lever intothe position shown in Fig. l. \Vhen the lower part of this footlever ispressed back in the direction of arrow 1, Fig. 1, the picker is raised,so as to lift the uppermost stay out of the holder G, and the cross-headI is moved toward the punch E, and, as the bell-crank lever J K has tofollow the motion of the cross-head, a cam, p, formed on the upper edgeof the long arm J of said bell-crank lever, strikes a stud, q, securedin one of the guides H, and by this stud the picker L is depressed, sothat the stay carried by the same is brought in contact with a device,Q, which serves to transmit paste or moisture from the fountain R to thestay, and

whichlhereinafter term transmitter. This transmitter is made of anabsorbent mate-.

rialsuch as sponge-and I prefer to make it in the form of a roller,which is mounted on the axis q". I

If a plain stay is used, the fountain is supplied with a suitableadhesive, such as paste; but if a previously-prepared stay is used thefountain is supplied with water or with a thin solution of mucilage, sothat one side of said stay on being moved along in contact with thetransmitter Q is rendered adhesive. After the cam p has passed the 'studq, the picker is slightly raised, and at the end of its forward motionit assumes the position shown in Fig. 2, carrying the adhesive stay overthe corn er of the box \V, which has been placed upon the die orbox-support F. As the picker approaches its forward position thepunch Ebegins to descend, and when the stay carried by the picker has reachedthe required position, with its median line over the corner of the box\V, it is depressed by the action of the punch E, the wings of thepicker being thrown into the position shown in Fig. The movement of thepunch E is produced by the action of a cam-groove, S, upon a lever, T,as will be readily understood by referring to Figs. 1 and 2. 'When thepunch E is depressed upon the picker, the cavity 1) in said punchaffords room for the hinge portion of the picker, while the inclinedfaces of said punch serve to carry the wings of the picker into theposition shown in Fig. 3.

hen the foot-lever P is swung back to the position shown in Fig. 1, thepickerL is caused to slide back over the transmitter Q, and in order toprevent the entire surface of said picker from being coated with pasteit must be formed with projections, (see Figs. 4 and 45%) and the pasteadhering to these projections will be sufficient to lift the uppermoststay out of the holder in the same manner in which the picker of anordinary envelope-machine takes up the envelopes. I

In the example shown in the drawings the transmitter Q-is made in theform of a roller,

which is mounted onthe axis q, and a revolving motion is imparted to thesame by any suitable meanssueh, for instance, as a toothed segment, X,which is geared together with the axis (1, and which swings on the stud0 of the foot-lever I and moves with this footlever.

The projections 1 in the picker are supported by springs 1 (see Fig. 4,)so that they recede when the punch comes down upon the picker.

hat I claim as new,and desire 1.0 secure by Letters Patent, is

l. The combination, with the box-support F and punch E, of the holder G,the fountain R, the transmitter Q, the picker L, and mechanism,substantially as described, for imparting motion to the picker and tothe punch.

2. The combination, with the box-support F and the punch E, of theholder G, the fountain R, the rotary transmitter Q, the picker L, andmechanism, substantially as described, for imparting motion to thepicker and to the transmitter.

The combination, with the box-support F and the punch E, provided in itsworkingface with the cavity 1), of the picker L, composed of two hingedwings, jj, and mechanism, substantially as described, for impartingmotion to the picker and to the punch.

i. The combination, in a machine for applying corner-stays to boxes, ofa box-support, a reciprocating punch for pressing the stay on the box, aholder for containing the stays, a reciprocating picker for picking upthe stays from the holder and carrying them to the box, and means,substantially as described, for operating the punch and the picker.

5, The combination, in a machine for applying corner-stays to boxes, ofa box-support, a reciprocating punch, a holder for containing the stays,a reciprocating picker for picking up the stays from the holder, andmeans, substantially as described, for rendering the stays adhesive. I

6. The combination, with a reciprocating punch, a box-support, and aholder for the cornerstays, of apicker for carrying the stays from theholder to the box, and means, substantially as described, for renderingthe picker adhesive.

7. The combination, with the box-support F, the punch E, the fountain R,the transmitter Q, and the picker L, of yielding projections Z fitted inthe picker, and mechanism, substantially as described, for impartingmotion to the punch and to the picker.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
